受激布里渊散射是光和行进声波之间的基本相互作用，并且主要由电致伸缩和光弹效应引起，其相互作用强度比其他相关非线性光学过程的相互作用强度大几个数量级。在这里，我们报告了一个高品质的回音壁模式光学微谐振器的布里渊散射诱导的透明度的实验演示。作为布里渊散射诱导透明的基础的三重共振受激布里渊散射过程大大增强了光-声相互作用，使光能够作为相干循环声波存储，寿命高达10 μs。此外，由于相位匹配要求，循环声波只能耦合到具有给定传播方向的光，导致非互易光存储和检索。这些独特的功能为集成低功耗、光隔离器和环行器的全光交换开辟了新的途径。 受激布里渊散射是一种非线性相互作用，允许光被存储为相干声波。在这里，作者报告了在光学微谐振器中布里渊散射诱导的透明性，其高质量允许长寿命的非互易光存储。
Stimulated Brillouin scattering is a fundamental interaction between light and travelling acoustic waves and arises primarily from electrostriction and photoelastic effects, with an interaction strength several orders of magnitude greater than that of other relevant non-linear optical processes. Here we report an experimental demonstration of Brillouin-scattering-induced transparency in a high-quality whispering-gallery-mode optical microresonantor. The triply resonant Stimulated Brillouin scattering process underlying the Brillouin-scattering-induced transparency greatly enhances the light–acoustic interaction, enabling the storage of light as a coherent, circulating acoustic wave with a lifetime up to 10 μs. Furthermore, because of the phase-matching requirement, a circulating acoustic wave can only couple to light with a given propagation direction, leading to non-reciprocal light storage and retrieval. These unique features establish a new avenue towards integrated all-optical switching with low-power consumption, optical isolators and circulators. Stimulated Brillouin scattering is a non-linear interaction that allows light to be stored as coherent acoustic waves. Here, the authors report on Brillouin scattering-induced transparency in an optical microresonator whose high quality allows for long-lifetime non-reciprocal light storage.
